Despite all positive effects of doping on the body they could be dangerous. Possible side effects of anabolic steroids can be avoided by choosing the right form (oral or injectable) and combination as well as by taking reasonable androgenic dosages. It has to be mentioned, that the most side effects of drugs disappear after the cycle is completed. Moreover, many of them can be blocked during the cycle by using respective supplements. Therefore, in order to avoid possible negative consequences one shall pay attention to studying information about the drugs prior to use them.
Individual states in the United States often ban these analog drugs by name as they appear. Since 2012, Louisiana has classified phenazepam as a controlled dangerous substance.  This ban affects several products, some of which were sold at retail stores under the guise of air freshener or similar, containing phenazepam yet claiming not to be for human use. This legislation was introduced after one such product, branded as "Zannie" and marketed as an air freshener rapidly gained publicity as the subject of numerous media reports, attracting the attention of officials. [ citation needed ] The ensuing investigation effort, led by Senator Fred Mills and Louisiana Poison Center Director Mark Ryan, positively identified the active ingredient of "Zannie" as phenazepam. According to Ryan, chemical analysis identified the active ingredient as "100 percent phenazepam". 
Pharmaceuticals such as Dexamphetamine Sulphate are legal if prescribed
and used by the person to whom they were prescribed. A small number of weaker
amphetamine-based compounds (. Benzphetamine) are Class C drugs.
OTHER INFORMATION: Amphetamines were once one of the core drugs on the UK drug scene. Recreationally they were popular in lots of music/club/youth scenes and diverted amphetamines were popular with mods, rockers, Northern Soul fans, and then a core feature in the punk scene and amongst some Goths.
Non-recreationally, amphetamines had long been a feature of the diet-pill world. They were also used in a number of workplace settings, including factory and warehouse work, fishing and driving settings, and amongst students and night workers. Ian Fleming's James Bond uses Benzedrine on several occasions in the course of work.
Speed has, in part been displaced by more popular, less harsh and more "glamorous" competitors, most notably Ecstasy and cocaine. The advent of Ecstasy, with a less edgy, more "loved-up" feel, made for a better clubbing experience and contributed to a decline in speed's popularity. Where cocaine was scarce and expensive, speed, although considered "poor man's coke" was an acceptable alternative. As availability of cocaine increased and price dropped, many people would choose to use cocaine over speed.
It had always been recognised that speed was a low purity drug at street levels, and the advent of legal, pure alternatives like mephedrone and later ethylphenidate contributed still further to a drop in speed's popularity.
Having said this, in large parts of the UK, speed remains the stimulant of choice, especially where cocaine is hard to obtain. In an increasingly contaminated "white powder" market, it's hard to know how many of the street blends are, in part, amphetamine.
